# Häxrök — Design Review for Your KiCad Projects Hobbyist boards often come back dead because of a single schematic mistake. A pull-up connected to the wrong rail. UART wired TX-to-TX. A regulator that can't start itself. Professional teams catch these problems through design reviews, reference designs, and simulation. Hobbyists? They post a screenshot to a forum and hope someone spots the mistake. KiCad's ERC won't catch them. The connections are electrically consistent. They're just wrong. **Häxrök brings professional-style design review to hobbyist KiCad projects.** Drop in your KiCad project folder and choose your mode: ### Review Before You Order Catch design mistakes before they become expensive PCBs. - **Ranked findings:** Issues classified as *Won't Work*, *May Fail*, or *Improvement*. - **Evidence:** Each finding points to the relevant schematic connections and explains why they matter. - **Actionable fixes:** Get a concrete schematic correction and a verification step to perform before ordering. - **Honest results:** If no issues are found, Häxrök says so. No invented problems. No noise. ### Debug on the Bench Your board isn't behaving as expected? Let's figure out why. - **Describe the symptoms:** Tell Häxrök what you observe on the bench. - **Get ranked hypotheses:** Receive plausible root causes, ordered by likelihood, with explanations grounded in your schematic. - **Follow bench procedures:** Get concrete steps for what to probe, measure, and test. - **Refine with measurements:** Enter your actual measurements, and Häxrök updates its hypotheses accordingly. **From schematic to working hardware, Häxrök helps you catch mistakes before they cost you a board—and troubleshoot them when they do.**
